An interesting take on the Ship of Theseus. My philosophical musings lead me to believe that it is changing every moment in its existence. However, for the sake of simple communication, it is _called_ the same ax so we don't have to differentiate between "the ax in this one instant" versus "the ax in this other instant".

So if we're talking metaphysically, then no, it is a different ax. However if we are taking a linguistic stance, then it is in fact the same one.

From a component repair standpoint it IS the same axe, it was repaired twice but it is still the same axe. But it is only the same axe in the way that creating a completely new car from spare parts would still be an assembled mass of spare parts
